What problem does this PR solve?
TiSpark may set the wrong range to TiKV when using
FetchHandleRDD
. We have two guesses about this:What is changed and how it works?
Since it is hard to find the root cause, we just log it and retry once when this error occurs. We use client-java's splitRangeByRegion method to avoid exceeding the bound issue. It seems this method can split the range correctly.
